防爆纖維簡介
防爆纖維是防爆化學纖維的簡稱,纖維是以聚丙烯為原材料,通過特殊工藝制造而成的,具有抗拉申、耐沖擊、提高整體強度;疏水、排氣、防龜裂、防爆裂;縮短烘烤周期、簡化升溫過程,提高整體使用壽命的一種特殊纖維。在定型與不定型耐火材料烘焙干燥過程中,為了便于水蒸氣壓力從砌體中得到及時釋放,防止砌體的爆裂而加入澆注料中的一種用添加劑。
纖維的作用機理在于十分均勻亂向分布在砌體中,形成由內(nèi)及外,由上至下的網(wǎng)絡體系,隨著烘焙溫度的提高,它開始軟化、收縮、熔化, 形成氣孔,原有的網(wǎng)絡體系變成了類似人體的汗毛排汗體系。將烘焙過程中產(chǎn)生的水氣壓力及時排出。而關鍵的纖維與纖維之間的搭橋聯(lián)接、排氣孔徑的大小,纖維在砌體中分散程度決定了砌體中排壓的效果。
金林防爆纖維有兩種:軟化點80與110,熔化點100與150。纖維加入耐火材料或建筑混凝土、灌漿料、工業(yè)地坪、干粉砂漿肌體中可有效縮短烘干時間,并且防爆纖維可以提高材料的整體抗折與耐壓強度等性能,迅速排出水蒸汽降低內(nèi)應力、防止爆裂、龜裂現(xiàn)象的發(fā)生。

防爆纖維性能
金林防爆纖維具有棧積比重小、分散性好、無燒結、無并絲、殘留少、使用效果佳等特點,是各種不定型耐火材料新型防爆劑,尤其適用于高強快干不定型耐火材料。
1、抗拉申、耐沖擊、提高整體強度。
2、疏水、排氣、防龜裂、防爆裂。
3、縮短烘烤周期、簡化升溫過程,提高整體使用壽命。
防爆纖維使用方法
1、摻量范圍:0.6-1.8kg/m3,混凝土抗裂防滲建議摻量0.9kg/m3。
2、長度選擇:砂漿建議用6-8mm,混凝土建議用12-19mm。
3、將粗細集料連同纖維一起加入攪拌機加水攪拌,適當延長時間使纖維在混凝土中均勻分散。
防爆纖維用途
1、混凝土剛性自防水結構、地下室底板、側墻、頂板及屋面樓板、水池等。
2、水泥砂漿、干粉砂漿、保溫砂漿、抗裂砂漿、內(nèi)外墻抹灰砂漿等。
3、抗裂、抗沖擊、抗磨損、抗震等要求的場合。
4、橋面、橋墩、港口碼頭、水利工程等。適用于各種散狀材料如涂抹料、澆注料等不定形耐火材料,應用效果尤為顯著。
防爆纖維運輸儲存須知
運輸與裝卸:在運輸過程中,不得用鐵鉤拖拽,應防止與堅硬物質混裝,不可強烈振動、磨擦、踩、砸,嚴禁拋擲,應輕裝輕卸,以減少包裝破碎,影響使用。
儲存:應儲存于陰涼干燥處,防止內(nèi)外包裝袋破裂,防止受潮和吸附空氣中其它物質,影響使用效果。嚴禁與有毒有害氣體或易揮發(fā)物質混放,存放要遠離污染源。

In shape and not stereotypes refractories for drying process, in order to facilitate water vapor pressure from masonry timely release, prevent masonry burst and join a special additive of castable. Riot fiber mechanism is very uniform random distribution in masonry, formed by inside and outside, top-down network system, with the improvement of baking temperature, it begins to soften, shrinkage, melting, finally formation porosity, the original network system into a system similar to human hair perspiration. Water vapour pressure generated in the roasting process in time. And key bridge between the fibre and fibre connection, exhaust aperture, the size of the fiber dispersion degree determines the masonry in the masonry out the effect of pressure. Explosion-proof fiber has two kinds: softening point 80 and 110 , melting point 100 and 150 . Fiber in refractory material or construction concrete, grouting materials, industrial floor, dry mortar can effectively shorten the drying time in the body, and explosion-proof fiber can improve the overall flexural and compressive strength of materials, such as performance, fast discharge steam to reduce internal stress, prevent the occurrence of burst and cracking phenomenon. Explosion-proof fiber performance Jin Lin explosion-proof fiber has the mass density is small, good dispersibility, sintering, and silk, less residue, use effect is good wait for a characteristic, is all sorts of new explosion-proof agent not stereotypes refractories, especially suitable for high strength fast dry not stereotypes refractories. 1. Tensile shen, impact resistance, increase the overall strength. 2. The hydrophobic, exhaust, against chapping, the blowout. 3. Shorten curing cycle, simplify the process of temperature, improve the service life of the whole. contact Shizuishan Jin Lin corundum refractories co., LTD Sales manager: li ching Contact phone number: QQ email: 2105787223 @qq.com Website: Address: takashi shizuishan pingluo county of ningxia hui autonomous region gang coal market 產(chǎn)品寫真 廠區(qū)實拍 聯(lián)系方式 石嘴山市金林剛玉耐火材料有限公司 銷售經(jīng)理:李晴
